Description

Technical Field

[0001] The utility model relates to the technical field of dust-free filling at docks, and specifically relates to an alumina dust-free bagging system. Background Art

[0002] Alumina is a white powder and the main material for making aluminum. The goods have good fluidity and usually have a specific gravity of about 1 t / m³. In port loading and unloading operations, the traditional alumina ship unloading and bagging operations generate a large amount of dust, which not only causes a large amount of cargo loss and waste of resources, but also causes serious heavy metal pollution. In addition, alumina dust particles cause serious harm to the human body function;

[0003] The traditional process flow is that the portal crane grabs the goods through a leak-proof grab and places them in the bagging machine. The weighing and bagging actions are realized through the bagging machine, and then the alumina ton bags are transported to the backcourt by equipment such as forklifts and flatbed trucks.

[0004] The alumina dust flying mainly concentrates in two links: when the grab grabs the material and sends it to the bagging machine, and when the bagging machine fills. First, there should be enough depth at the upper feeding port of the bagging machine to enable the grab to extend into the hopper for discharging. Since the material falls under the action of gravity and the resistance between particles when the grab discharges each time, there will still be some materials flying upward due to the mutual collision between particles when discharging each time. In order to achieve a better dust suppression effect, it is best to have wind blocking and dust suppression measures at the grab discharging place and the bagging port. Controlling these two links controls the material loss and environmental pollution. Under the high-pressure environment of strict environmental protection requirements, the control of aluminum powder dust during the loading, unloading and bagging of alumina powder is an urgent problem to be studied and solved. The integrated equipment with dust suppression function has a large investment, and the supply market changes uncertainly. Once there is no support from sufficient supply volume, the investment in new equipment will also increase certain pressure and risks to the company's production and operation.

[0005] Therefore, considering comprehensively, the company uses the original dust suppression funnel for transformation, and adds a small-sized and highly integrated automatic bagging machine under the dust-proof funnel for combined operation with the original dust-proof funnel.
